Web Services Book for Newbie

I am completely new to Web Services. Currently I have a copy of "Designing Web Services with the J2EE 1.4 Platform" from Sun Microsystems. As an introductory book, is it good enough? It was published in 2004 which is a bit outdated. But since I have a copy of it, I just want to hear some of your recommendation before looking for more updated titles like Oreilly's Java Web Services Up And Running.

Hi!
"Designing Web Services with the J2EE 1.4 Platform" is, in many aspects, a good read despite its age. It is now, however, a good introduction on web services.
I would recommend having at least some understanding of the basic concepts of web services before reading the above book.
A book containing good introductory material is "J2EE Web Services" by Richard Monson-Haefel - the part on JAX-RPC can be skipped if you intend to work with JAX-WS.
Best wishes!
